You will need to verify compatibility with DPM as they make no mention of the X-frame models or the M18/M17 and we do not have information as to whether the guide rods between the standard P320 models are interchangeable with the X-frame or M18/M17 models.

the M18 is nothing more than a p320 compact/carry with a safety and a full size grip/magazine. all the other parts are identical as I own both and interchange parts/grips/and slides.

It DEFINITELY works on the M18 which is 3.9" barrel same as compact and carry version. M17 requires the full size kit to accommodate the 4.7" barrel
